While your factory brakes do a decent job of bringing your Focus to a halt, they really struggle in applications where hard, consistent braking is needed. Here at Stage 3, we have you covered with some of the best braking upgrades available on the market to equip your fast and sporty Focus ST with stop-on-a-dime performance and control from any speed. If you have a 2014 Focus ST, it's crucial that you know your ST's build date, as ones built before 3/31/14 come with 12.6" front rotors, while those built after 3/31/14 come with 13.2" front rotors. The rear rotors have remained the same since the ST debuted in 2013. Also be sure to check out our ST Turbo Upgrades!
The stock blank rotors and factory semi-metallic brake pads on the 2013-2019 Focus ST are decent enough for the average daily driver, but if you drive the turbocharged EcoBoost ST the way it was meant to be driven, upgrading to a high-performance braking system is the only way to safely control all of that power. The good news is that, here at Stage 3, we have you covered with one of the greatest rotor and brake pad selections on the market. StopTech's Slotted Front Rotors and Slotted Rear Rotors feature exclusive Vac-U-Slots that are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean which is especially helpful in wet weather conditions. They are up to 8 pounds lighter than stock and improve your cooling, braking, acceleration, and handling. Paired up with the innovative and exciting Hawk HPS Front Brake Pads and HPS Rear Brake Pads, you get the kind of one-two punch combination that you need to knock out the competition on the streets or racing at the track.
The root of the confusion behind the Focus ST's braking system is the split in rotor size that came about mid-2014. When Ford decided to increase the size of the ST's front rotors from approximately 12.6" to 13.2" , they did it in the middle of a model year, causing a split in the 2014 model year as to which size rotors are equipped.
The change in rotor size was implemented starting 3/31/2014, meaning if your ST was built after that date, your front rotors are 13.2-inches in diameter. Any STs built before 3/31/14 come with 12.6" rotors. The easiest way to check your ST's build date is to go here and enter your car's VIN.
